We watched Season 2 and tried to watch season 3 thru Amazon but they wanted money per episode sooooo DH went and bought season 3. We finished watching it over a week ago and while I was cleaning the house last Saturday, I watched the 3rd season again. LOVE, LOVE IT! I can't believe that it may take another two years for Season 4. I won't make it! Love all characters. Mrs. Hudson is just plain precious!
